There are 2 squares, and the ratio of their perimeters is 5:8. If the area of the first square is 225m², then what is the area o

nata0808 [166]

we know that

the ratio of the perimeters is equals to the scale factor

scale factor=5/8

scale factor=measure smaller square/measure larger square

let

smaller square=first square

larger square=second square

area smaller square=[scale factor]²*area larger square

area larger square=area smaller square/[scale factor]²

scale factor=5/8

area smaller square=225 m²

area larger square=225/[5/8]²----> 225/(25/64)-- > 225*(64/25)----- > 576 m²

the answer is

the area of the second square (larger square) is 576 m²

Slick Slack is a downloadable app that can be used to automatically generate excuses for being late to work based on the weather

Greeley [361]

Answer:

$(x_1,y_1) = (1,5840)$

$(x_2,y_2) = (2,13090)$

$y = 1812.5x + 4027.5$

$y_0 = 4027.5$ --- y intercept

Step-by-step explanation:

Given:

x = weeks; y = copies

The right parameters are:

After 1 week, 5840 copies were downloaded

After 5 weeks, 13090 copies were downloaded

So, the (x,y) forms are:

$(x_1,y_1) = (1,5840)$

$(x_2,y_2) = (5,13090)$

Next, we calculate the slope (m) using:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{13090 - 5840}{5 - 1}$

$m = \frac{7250}{4}$

$m = 1812.5$

The equation is then calculated using:

$y = m(x - x_1) + y_1$

$y = 1812.5(x - 1) + 5840$

$y = 1812.5x - 1812.5 + 5840$

$y = 1812.5x + 4027.5$

To calculate the y intercept, substitute 0 for x

$y_0 = 1812.5*0 + 4027.5$

$y_0 = 0 + 4027.5$

$y_0 = 4027.5$

John can ride his skate board 100 feet in 4.6 seconds. how fast is this in miles per hour?

diamong [38]

About .24 mile per hour
$60 \div 4.6 = 13.04 \\ 13.04 \times 100 = 1304.34$
1 mile is 5280 foot
